Computers Inside and Out

Computers Inside and OutAnswersYour instructions were to define, describe and identify the computer vocabulary from the text provided, Computers Inside and Out.

And some vocabulary, you just had to figure out on your own.

InputInput is information that goes IN to a computer.What are some things you can input into a computer?Give some examples of input devicesOutputOutput is information that comes OUT of a computerName some examples of output devicesStorageStorage is where data is kept.Name some examples of storage devicesProcessingComputer Processing is the execution of computer instructions. When a computer processes a software program, it performs the commands written in the programming code.In a computer, where does the processing take place?CPU (Central Processing Unit) SoftwareComputer software is any set of machine-readable instructions that tells a computer's what to do. Computer programs are software.The term is used to contrast with the computer hardware that carries out the instructions. Hardware and software require each other and neither has any value without the other.

HardwareHardware refers to the physical parts of a computer system. Some basic computer hardware includes the motherboard, CPU, RAM, hard drive, and BIOS chip.ProgrammingProgramming is the act of creating the set of instructions (program) that tell a computer what to do.Name some examples of a computer programRandom Access MemoryRAM (Random Access Memory) stores data and programs on a temporary basis. When you turn off the computer, the data in RAM disappears.The amount of RAM you have affects how fast your computer can process information.

Hard DriveThe hard drive is what stores all your data on a permanent basis. When you turn off your computer, data on your hard drive is unaffected.A typical hard drive is only slightly larger than your hand, yet can hold over 100 GB of data. Read Only MemoryRead Only Memory holds data that is permanent and cannot be changed.ROM is used to hold the instructions that the computer needs to boot up, before the system software loads.What is an example of a ROM chip?BIOS (Basic Input/Output System).

DataComputer data is any information processed or stored by a computer.MediaMedia refers to anything that holds information (data). A book is media. A Blu-Ray disc is media.Can you give some examples of computer media? Hard drives, removable drives (such as Zip disks), CD-ROM or CD-R discs, DVDs, flash memory, USB drives.

MicroprocessorA microprocessor is a small chip inside a computer or other electronic device, that receives input, processes it, and produces output.What is the main processor (the brain) of a computer called?CPU (Central Processing Unit)BinaryBinary (or "base-2") is a numeric system that only uses two digits 0 and 1.

BitA bit (short for "binary digit") is the smallest unit of measurement inside a computer. It contains a single value of 0 or 1.Bits are often grouped together in 8-bit clusters called bytes.

PixelThe term pixel is actually short for "Picture Element." These small little dots are what make up the images on computer displays,A computer screens resolution is measured in pixels...History of ComputersAnswer reviewWhat are considered to be the true ancestors to todays computer?

Some of the ancestors or todays computers include:The abacusMechanical calculatorsThe Analytical EngineWho invented the Analytical Engine?Charles BabbageWho programmed the Analytical Engine?Ada Byron King (the Countess of Lovelace) programmed the Analytical Engine. She is considered the mother of computer programming.What is hardware?Hardware refers to the physical parts of a computer system. Some basic computer hardware includes the motherboard, CPU, RAM, hard drive, and BIOS chip.What is software?Computer software is any set of machine-readable instructions that tells a computer's what to do. Computer programs are software.The term is used to contrast with the computer hardware that carries out the instructions. Hardware and software require each other and neither has any value without the other.

What is a microprocessor (CPU)?The microprocessor is the brain of the computer. The Central Processing Unit (CPU) controls what a computer does.What is an input device? List an example.Any device that lets you put data IN to a computer.Examples include: KeyboardMouseDigital CameraThumb driveCDWhat does ROM stand for?Read Only MemoryThis is information that cannot be changed. What does RAM stand for?Random Access MemoryThe computer uses RAM for temporary storage of information.What do you call the place where you store information that will be used again and again?. Long-term storage What devices are used for long term storage?ROM (Read Only Memory)Hard driveThumb driveCDs/DVDsWhat is output? Give example of output devices.Output is any data that comes OUT of a computerExamples include:PrinterMonitorSound from the computer speakersMP3 fileWhat is binary code?Binary (or "base-2) code is a numeric system that only uses two digits 0 and 1.

What are the 2 numbers in that computer code, and what do they represent?

The numbers Zero and OneZero represents off and One represents onWhat is a bit?A bit (short for "binary digit") is the smallest unit of measurement inside a computer. It contains a single value of 0 or 1.Bits are often grouped together in 8-bit clusters called bytes.

What is a pixel?The term pixel is actually short for "Picture Element." These small little dots are what make up the images on computer displays,A computer screens resolution is measured in pixels.
